A PPARA I'US FOR VENTILATING, HEATING, AND COOLING BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 284,14( dated August28, 1883.

' Application filed November 2, 1882. (No model.) I

To all whom it may concern.-

Be it known that I, THOMAS MCGRORY, of

Q Philadelphia, in the county of Philadelphia,

and in the State of Pennsylvania, have invented certain new and usefulImprovements in Apparatus for Ventilating, Heating, and CoolingBuildings, &c.; and I do hereby declare that the following. is a full,clear, and exact description thereof, reference being had to theaccompanying drawing, and to the letters of reference markedthereon,-making a I part of this specification.

This invention relates to certain improvements in heating, ventilating,and cooling buildings, andit has principally for its object toutilizethe waste heat from steam-boiler or other furnaces for heating andVentilating I purposes, as more fully hereinafter specified. This objectI accomplish by the means illustrated I in the accompanying drawing, inwhich is represented a sectional View of my invention.- I

The letter A indicates the .walls of i a building of any description;-B, one of the floors thereof; G, aroom or a cellar inthe lower part ofthe building, and D E two upper rooms.

The letter F indicates a steam-boiler, which may be of any description,but which is in the present instance in the form of an ordinaryhorizontal tubular boiler, having a flue,

I G, for the escape of the products of combustion, and the usualsmoke-stack, H. The said boiler is surrounded by a jacket, K, into whichextends the lower end of a pipe, L, which is extended up through thesmoke I stack, and is provided with a coil orseries-of return-bends, M,the upper end extending I I laterally through the smoke-stack and termi-T, which connects with branchesU, entering nating in a funnel, N, at itsupper end, as indicated. The boiler is located in the lower room orcellar, in which is also located a steam-engine, O, the fly-wheel ofwhich drives a fan-blower, P, by means of a belt,R. The

means of pipe S and S, withthe upper part of the jacket beforementioned. From the reduction-port of the blower extends a pipe,

cated by the letter V, and with a register, W, in the other. I

The lettenX indicates a pipe leadingfro the pipe S up through the wallof the buildbe extended to the exhaust-fan, as seen and indicated bythedott-ed lines, in which instance it is carried' through the fire-box,and then to the fan. NVhen this form of con struction or arrangement isadopted, the pipe S and the jacket are dispensed with, and a cock, B, isapplied to the pipe. When the casing is not employed, the pipe L may 'bemade to enter through the boiler-spaceor the fire-chambers, or throughboth to the fancase. r

The operation of my. invention is as follows; The hot products ofcombustion, passing out through the smoke-stack, heat the pipe and coilleading through the same. The air draw-n throughthe said pipe and coilby the exhaustfan passes through the jacket, or, in some in stances-aswhen the said jacket is dispensed withdirectly through the said pipe,being 1 heatedon itsway, as above indicated, and may be delivered to theradiator to heat the rooms above in winter byopening the cock B, thecock A being closed. In. warm Weather the cock B is closed and the cockA opened, permitting cold air to be supplied to the rooms above.

In some instances I propose to use awatermotor to operate theexhaustfan.

I am aware that it is not broadly new to divide a smoke-stacker chimneyin such a manner asto form smoke and air conduits,

and do not for this reason desire tobe understood as claiming such.

Having thus described my invention, what I claim, anddesire to secure byLetters Patent,

The combination, in an apparatus for ven- I the respective rooms above,and connecting tilating, heating, and cooling buildings, of the I00, 3
